Barun Roy: The geothermal alternative

While wind and solar power remain the principal force driving the world’s move towards alternative energy, the search is now also beginning to gather pace for another potential resource that has been little pursued so far: energy that exists in the heat of the Earth and, once on tap, is cheap, reliable, virtually endless, and available throughout the year. The technology is there, the need is growing, and nations must act more aggressively to reduce the danger to the environment from fossil fuels. All this forebodes a better future for geothermal energy, and, significantly, Asia will be playing a leading role in its revival.
